Description Andrej Nemec 2017-03-20 09:51:35 EDT 
An issue was discovered in Erlang/OTP Erlang's generation of compiled regular expressions is vulnerable to a heap overflow. Regular expressions using a malformed extpattern can indirectly specify an offset that is used as an array index. This ordinal permits arbitrary regions within the erts_alloc arena to be both read and written to.
